      One week after a series of earthquakes rumbled through Alaska’s Aleutian Islands, seismic activity continued in the area this past weekend.

      A 6.0-magnitude tremblor, as measured by U.S. Geological Survey, struck on December 1 at 8:01 p.m. local time (9:01 p.m. B.C. time).

      The epicentre, at a depth of 27 kilometres (17 miles) was situated 127 kilometres (79 miles) southwest of Adak, Alaska.

      The U.S. Tsunami Warning Centre stated that a tsunami was not expected from this seismic event.

      Not long after, it was followed by a 4.3-magnitude quake at 9:41 p.m. local time (10:41 p.m. B.C. time) in the same area.

      According to the U.S. Geological Survey, the epicentre was at a depth of 35 kilometres (22 miles) and was 124 kilometres (77 miles) southwest of Adak.
